Cool! Look what I learned how to do with the "create a pattern bush" direction from Illustrator's Help section:Ignore the ugly patterns. They are the generic swatches included in Illustrator's patterned swatches. See the leopard print? It is set to only show up when I do sharp corners. The tan square one is set to appear at the end of the brush - I guess between the last two anchor points. The middle pattern is for loops, I guess, and has a great kaleidoscope effect when it's stretched and looped. This should be fun when I make my own patterns!
